(i) Various materials have been obtained by Vapor Physical Evaporation (VPE), including topological insulators and Nodal line semimetals.
(ii) Fruitful topological phenomena, e.g. spin-momentum locking and anisotropic Shubnikov-de Haas effect in in type-II Weyl semimetal, as well as giant planar Hall effect in Dirac semimetal are explored through systematically analyzing magnetic and electrical properties.
Anisotropic chiral anomaly in WTe2 nanoribbons verfies the Type-II Weyl semimetal.
Nontrivial Berry phase, chiral-anomaly-induced negative longitudinal magnetoresistance, giant in-plane anisotropic magnetoresistance as well as giant planar Hall effect are observed in ZrTe5−δ nanoplates, confirming coherently that ZrTe5−δ is a Dirac semimetal.
(iii) The application of topological phenomena in spintronics, e.g. spin-momentum locking and the spin-orbit torques in heterojunctions.
